Abstract: A water cooler is arranged to receive a bottle member in an inverted orientation thereto, with the water cooler having a top well and an associated opening to receive the water bottle. The top wall includes a top wall flange mounting a torroidal collar, with the torroidal collar positioning a filter member within the water cooler, wherein the filter member includes an inner wall and an outer wall with filtration material therebetween. The inner wall includes inner wall apertures cooperative with outer wall apertures directed through a floor of the outer wall, with the inner wall apertures oriented through the inner wall adjacent an upper end of the filter member to maximize filtration of water through an associated filter material. The invention is arranged to further include a flotation container to permit imparting of additives into the water as desired.
